Thanks for your detailed response, Ovid. I have looked at Test::Class::Moose before, but our use case is slightly different from what I understand Test::Class::Moose is providing.
We’re using Perl to test a storage system and an example test case would for example be: “Write data to the storage system and after the I/O has started reboot the storage system”. So you see that these are not 2 independent test cases that we want to run in parallel but instead a single test case that uses multiple threads or processes – 1 process for the I/O and 1 process for the system operation. That’s where we use Test::ParallelSubtest which provides a simple interface to run test steps in parallel.

I've also uploaded a new slide deck for Test::Class:Moose[3] and it explains some new features, or you can watch a video about it (which is just a touch outdated, but all examples work)[4]. Note that for Test::Class::Moose, I've just uploaded 0.42. It fixes a subtle issue that one company ran into. You can wait for it to hit the CPAN or grab it from github[5]. 1. http://search.cpan.org/dist/Fennec/lib/Fennec.pm#RUNNING_FENNEC_TEST_FILES_IN_PARALLEL 2. http://search.cpan.org/dist/Test-Class-Moose/lib/Test/Class/Moose/Role/Parallel.pm 3. http://www.slideshare.net/Ovid/testclassmoose 4. http://www.youtube.com/watch?v=S1Z5_Ba860g 5. https://github.com/Ovid/test-class-moose I don't know much about Fennec, but the author seems competent and responsive. As for Test::Class::Moose, it's listed as BETA, but I know companies are already using it in production.

[github #290] [github #364] (Brendan Byrd) I’m now wondering how to solve this issue. It looks like Test::ParallelSubtest is not actively maintained. Is there a recommended alternative for it to run multiple tests in parallel? Thanks, Jan
